CIRCUIT FOR COIN-COLLECTORS.

Serial No. 300,929.

To all whom it may concern:

it known that I, JAMES L. MoQuMuuE, a citizen of the United States,residing at Chicago, in the county of Cook and State of usefulImprovement in. Circuits for Coin- Uelleotors, of which the following isa full, clear, concise, and exact description. My imrention relates to acoin collecting telephone system,

{)ne of its objects is to provide a signaling circuit having contactsadapted to be controlled 9 plurality of coins. v A tum r object of myinvention is to provide an improved arrangement of line and cordcircuits, by which the operator at the central ollice can provide Forthe proper disposal coins deposited in the subscribers coin receivingapparatus without waiting for the subscriber to hang up his receiver,thereby relieving the system of drag.

My invention is adapted for use with coin collectors where the dc )ositof one or more coins, as the case may be, is required of the callingsubscriber. in order to reliey'e such systems of drag, due to theoperator having to wait until the subscriber hangs u his receiver beforethe coin can be returne to him, in case the desired connection is notestablished, I have introduced into the cord circuit a relay, whichlooks the refund battery incircuit with the subscribers line. Thecircult of the coin controlling magnet is so arranged that soon as thesubsc 'ibcr hangs up his receiver, the circuit from the battery iscompleted through the magnet, which thereupon operates mechanism in theusual manner for properly disposing of the coins.

- Iuu'll describe my invention more partic ularly by reference to theaccompanying drawings, which is a diagrammatic view showing a line andcord circuit embodying my invention, and illustrating by means ofconventional symbols the apparatus at a subscrib'ers station and at thecentral ollice.

The cord and line circuit I have chosen to illustrate my invention with,are of wellknown types, and hence a detailed de.scI'i],)--

tion of the familiar featuresthereof isunnecessary. 1

Referring to the drawii'igs, the branch circuit g from the tip side ofthe line is provided 7 with the usual polarized magnet M for controlling the disposal of: a coin or coins 7c, ls, deposited by thesubscriber In his com rc- .key.

. not Mr qun'ed irom the subscriber and coin l: has

eeiving apparatus. The contact a is normally open, wlnle'contact 1) 1snormally closed. The-coin 0, first deposited, closes contact (t andgrounds the branch circuit, Illinois, have invented a certain new and 5thereby operating signal L at the. central office in the usual manner.The deposit of the second coin 7r, in cases where 'two or more coins arerequired for connection, opens the contact 7), the branch circuit beingthen grounded at the subscribers station, through a shunt of contact I),only when the telephone hook is down, since the contact l) in said shuntis otherwise open. Since the de osit ol' the second coin removes theground rom' the branch line g, the operation of the test key 0 would notclose a circuit from the common central ollice battery through the relay0. The contact 0 is normally open and, unless the relay c is ener izedto close said contact, the test lam Hence the failure of tie test lampto light f1 is not lighted indicates to the operator that the secondpose a drag on the system to require the oporator to wait until thecalling party hangs up his receiver before she operates the refund Inorder to eliminate this drag, a relay 6 has been introduced into thecord circuit. \Vhen the refund lieyfis operated, the circuit from thebattcryj" is grounded through contact f The relay 0 which has a windingincluded in said circuit operates its armature c and closes a lockingcircuit through contact a". This circuit may be traced from groundthrough battery f, winding of relay 6, con tact 6*, over the tip side ofthe line, through thesubscribods set in case its receiver is oil itshook, over the ring side of the line, through relay s, contact 0*, whichis closed by relay (1, to ground. In case only one coin c has beendeposi l 2d, the circuit over the tip side of the hue would, of course,be groun ed throu h the normally closed contact I), and upon t isoperationol' keyf the coin would be immediately refunded by theoperation of the mag- In case two or more coins were realso beendeposited, the ground through magnet M would be completed throughcontact b as soon as thesubseriber hangs up his receiver. It isapparent, therefore, that the operator, without waiting for thesubscriber to hang upihis receiver, may operate the refund keyf. andthereby provide for the return of the coins to the calling; subscriberwithout further attention on her part.

Having thus described my invention, 1 claim 1. The combination with atelephone line extending from a subscribers station to a central ollice,of a coin receiving apparatus at the subscribens station, anelectromagnct, mechanism operated by the energization of said magnet fordisposing of a coin deposited in the coin receiving apparatus, means atthe central o'llicc for impressing current upon the telephone line, andmeans at the subscribei"s station, automaticaltv operated upon thesubscriber hanging up his receiver, to apply said current to theelectromagnet.
